Preferably, pure water or oil is used as the medium, and the radiator is a fin radiator.
Considering that the hot-melt welding requires a large current, an enlarged contact surface is required between the power supply module and the left and right lower electrodes 22 and 32, so that it is not recommended to directly connect the left and right lower electrodes 22 and 32 by using a wire. In order to provide a sufficient current and reduce the loss of the current, in this embodiment, the left transition piece 24 and the right transition piece 34 are both conductors, the lower left conductor and the lower right conductor 35 are respectively disposed below the left transition piece 24 and the right transition piece 34, and the upper left conductor 23 and the upper right conductor 33 are respectively disposed above.

In this embodiment, it can be seen that the lower h-shape of the left and right mounting blocks 21 and 31 also hold the sides of the left and right upper conductors 23 and 33, respectively.
Preferably, the left transition piece 24 and the right transition piece 34 have a length of 30-50cm and a thickness of 1-2cm at both front and rear ends, and the inner diameter of the liquid passage 61 is 70-80% of the thickness of the corresponding left transition piece 24 or right transition piece 34.

Wherein the backwater is bent and hidden in the frame 10; since the left and right transition pieces 24, 34 will move part of the way left and right, a portion or the whole of the return water is bent using an elastic tube to provide the proper amount of deformation. In another embodiment, the left transition piece 24 and the right transition piece 34 are each provided with two liquid passages 61, referring specifically to FIG. 5, in which the arrows indicate the direction of media flow. In this embodiment, the medium may carry away more heat.
Preferably, both the inlet and outlet of the liquid channel 61 are welded with adapter tubes, where the ends of the tubing 62 are wrapped around the adapter tubes and then reinforced with collars around the ends of the tubing 62. This design significantly improves the tightness of the conduit 62 with the liquid channel 61. Specifically, after the transfer tube is inserted into the liquid channel 61, a circle of welding is performed on the circumferential direction of the transfer tube, the welding part is sealed, and the circumferential direction of the pipe 62 can be locked by using a clamping ring after the pipe 62 wraps the transfer tube.

The power supply module supplies power, the heavy current forms a current loop through the notch of the steel ring 70, the power-on time lasts for about 3s, and the notch of the steel ring 70 heats and melts and is fused again after the power supply module is powered off. The second pushing mechanism 27 and the third pushing mechanism 37 are released, the upper left electrode 26 and the upper right electrode 36 are lifted, the first pushing mechanism 12 is reset, the right mounting seat 31 is far away from the left mounting seat 21, and the steel ring 70 after welding can be removed.
